Answer:
5
Step-by-step explanation:
Angle sum property formula
(n-2)180 (where n is the number of sides)
=>(n-2)180=540
=>n-2=540/180
=>n-2=3
=>n=3+2
=>n=5
I think it's 240 mile per hour
60sec.= 1min
60min.=1hour
60×60=3600secs.
3600÷15=240
Answer:
39 square meters.
Step-by-step explanation:
9 times 3 is 27. You have two triangles with length and width of 9 and 3 so you multiply it and get 27. You also have two smaller triangles of 3 and 4 and if you combine them it is really just a square. It is 3 times 4 which is 12. Now, the answer is 12 + 27 and you get 39 square meters. Hope it helps.
